篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了使用java方式装配Bean相关的知识，希望对你有一定的参考价值。
首先创建一个项目
然后是项目名
下图：
创建完项目先配置pom.xml依赖关系
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.csw.ssm</groupId> <artifactId>SpringBean</artifactId> <version>1.0-SNAPSHOT</version> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <maven.compiler.source>1.8</maven.compiler.source> <maven.compiler.target>1.8</maven.compiler.target> <spring.version>5.1.0.RELEASE</spring.version> </properties> <dependencies> <!-- Spring Web MVC --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!-- https://mvnrepository.com/artifact/org.hibernate.validator/hibernate-validator --> <dependency> <groupId>org.hibernate.validator</groupId> <artifactId>hibernate-validator</artifactId> <version>6.0.13.Final</version> </dependency> <!-- servlet 系列的支持 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>8.0</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>5.1.7</version> </dependency> <!-- Springframework --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.9.1</version> </dependency> <!-- MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.4.6</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.2</version> </dependency> <!-- 数据库驱动以及数据库连接池--> <dependency> <groupId>org.mariadb.jdbc</groupId> <artifactId>mariadb-java-client</artifactId> <version>2.3.0</version> </dependency> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency> <!-- 日志框架 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- https://mvnrepository.com/artifact/org.apache.poi/poi --> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi</artifactId> <version>4.0.0</version> </dependency> <dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.0.0</version> </dependency> <!-- 通用工具 --> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.9.7</version> </dependency> <!-- 单元测试 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> </dependencies> <build> <finalName>contact</finalName> <plugins> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.7</version> <dependencies> <dependency> <groupId>org.mariadb.jdbc</groupId> <artifactId>mariadb-java-client</artifactId> <version>2.3.0</version> </dependency> </dependencies> </plugin> </plugins> </build> </project>
在resources下配MyBatis文件generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!--jdbc 驱动包，等--> <!--<classPathEntry location="/Program Files/IBM/SQLLIB/java/db2java.zip" />--> <context id="sss" targetRuntime="MyBatis3Simple"> <commentGenerator> <property name="suppressAllComments" value="true" /> </commentGenerator> <jdbcConnection driverClass="org.mariadb.jdbc.Driver" connectionURL="jdbc:mariadb://localhost/student" userId="root" password="13794709305"> </jdbcConnection> <javaModelGenerator targetPackage="com.csw.entity" targetProject="src\\main\\java"> <property name="trimStrings" value="true" /> </javaModelGenerator> <sqlMapGenerator targetPackage="mapper" targetProject="src\\main\\resources"> </sqlMapGenerator> <javaClientGenerator type="XMLMAPPER" targetPackage="com.csw.dao" targetProject="src\\main\\java"> </javaClientGenerator> <table tableName="%"> <property name="useActualColumnNames" value="true"/> </table> </context> </generatorConfiguration>
配置jdbc.properties.xml
jdbc.driver=org.mariadb.jdbc.Driver
jdbc.url=jdbc:mariadb://localhost:3306/student
jdbc.user=root
jdbc.password=13794709305
jdbc.txType=JDBC
配置日志文件logback.xml
<?xml version="1.0" encoding="UTF-8"?> <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern> %msg%n </Pattern> </layout> </appender> <logger name="com.csw.dao" level="debug" additivity="false"> <appender-ref ref="STDOUT" /> </logger> <root level="error"> <appender-ref ref="STDOUT" /> </root> </configuration>
配置mybatis-config.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <!-- 使用jdbc的getGeneratedKeys获取数据库自增主键值 --> <setting name="useGeneratedKeys" value="true" /> <!-- 使用列别名替换列名 默认:true --> <setting name="useColumnLabel" value="true" /> <!-- 开启驼峰命名转换:Table {create_time} -> Entity {createTime} --> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> <!--<!–定义一些可以复用的变量–>--> <!--<properties resource="jdbc.properties" />--> <!--<settings>--> <!--<setting name="cacheEnabled" value="true" /> <!– 开启二级缓存 –>--> <!--<setting name="autoMappingBehavior" value="PARTIAL"/>--> <!--<setting name="mapUnderscoreToCamelCase" value="true"/>--> <!--<setting name="localCacheScope" value="SESSION" />--> <!--</settings>--> <!--<!–设置别名，可以简化在 xml 中的完全限定名的使用–>--> <!--<typeAliases>--> <!--<package name="com.csw.entity" /> <!– 可以跟 @Alias 结合使用 –>--> <!--</typeAliases>--> <!--<environments default="prod">--> <!--<environment id="prod">--> <!--<transactionManager type="JDBC" />--> <!--<dataSource type="POOLED">--> <!--<property name="driver" value="${driver}"/>--> <!--<property name="url" value="${url}"/>--> <!--<property name="username" value="${username}"/>--> <!--<property name="password" value="${password}"/>--> <!--</dataSource>--> <!--</environment>--> <!--</environments>--> <!--<databaseIdProvider type="DB_VENDOR">--> <!--<property name="mysql" value="mysql"/>--> <!--<property name="SQL Server" value="sqlserver"/>--> <!--<property name="DB2" value="db2"/>--> <!--<property name="Oracle" value="oracle" />--> <!--</databaseIdProvider>--> <!--<!–指定映射器–>--> <!--<!–<mappers>–>--> <!--<!–<mapper resource="mapper/xxx.xml" />–>--> <!--<!–</mappers>–>--> </configuration>
配置spring-web.
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans " xmlns:mvc="http://www.springframework.org/schema/c" xmlns:contxt="http://www.springframework.org/schema/p"> <!--跨域的配置--> <mvc:cors> <mvc:mapping path="/xxx" allowed-origins="http://localhost:8080" allowed-methods="GET,POST" allowed-headers="Accept-Charset,Accept,Content-Type" allow-credentials="true" /> <mvc:mapping path="/yyy/*" allowed-origins="*" allowed-methods="*" allowed-headers="*"/> </mvc:cors> <!--<!–配置验证器–>Spring装配bean--02通过Java代码装配bean
